SEAL-LOCK.

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed November 25, 1918. Serial No. 263,958. Y

To all whom it may concern:

Be itknown that I, HERBERT W. DAGGS, a `citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Seal-Locks, of which the following is a specification.

TheA present invention relates to seal locks and more particularly to the type in which a shackle interlocks with a casing in such a manner that a complete or partial destruction of a part'of the seal is required in order toopen the sealed structure, an object of this invention being to provide connection between the shackle-and the casing which lwill permit that portion of the shackle which interlocks with the structure to be secured, to lie in close proximity to the casing of the seal in order that the in-troduction of a rod or other instrument between the latter and the seal casing for the purpose of breaking the seal, will be prevented.

Another object of the invention is to provide a casing which has openings in two opposite walls, the openings in one wall' being alined with thev openings in the other wall,

in order that the arms of the shackle may be projected through both walls; and in this way such arms may be withdrawn from the-casing of the Aseal' if the shackle be cut at -two points adjacent the connecting portion between theA two arms, thus permitting the seal casingto be again employed with another shackle. j s

A further object of the invention is to provide a sealing device which would be J held bythe shackle to the casing andV at the same time will be so arranged as t beV readily inspected.

The invention consists of j certain parts and combination of parts, all of which will be hereinafter described. vandfmore particularly pointed out in the appended claims.

In the drawings v Figure 1 is an inside view of one of th members of the seal casing showing the shackle associated therewith; l Fig. 2 is the side view of the casing member shown in Fig. 1 with the shackle associated therewith, a part of the casing being in section;

Fig. 3 is a top view of the other member of the casing, showing the shackle clutch-7 ing means mounted thereon;

Fig.' s is a Section on the une 8 8 Off Fig. 7;

Fig. 9 is a front view of the seal con nected to a part to be sealed, the sealing being shown 'in' position on the casing.

The seal comprises ashacklefand a cas-V ing with which thel shackle interlocks. The shackle lis'preferably of a U shape' and made in this instance from wire withl the opposed faces of its two arms provided l'withy a series ofshoulders 2 to which lead inclined facesv 3,' these shoulders and `faces be ing provided in order that a clutching means arranged within the casing will cooperate therewith to prevent the withdrawal of the shackle from the casing.

The casing in the illustrated embodiment is formed by two members; one being illustrated in Figs. 1 and 2 and the other section '85 member illustrated in Figs. 1 and 2has a beingY illustrated in Figs. 3 and 4. The

rear wall 4, top and bottomv walls 5 and 6 respectivelvand sidewalls 7 The top and bottoni walls 5 and 6, are each provided with two openings 8, the openings in the top wall being alined with those in the bottom wall, f

so thel arms of the shackle after passing'V through the .opening of the top wall, may

` pass through the openings of the'bottom wall in v'order'that their free ends lmay project from the casing. The other casing member illustrated in Figs. 3 and 4, embodies a fronti wallV 9 and the two side walls 1 0, which are secured between the side walls 7 of the first described:casing memberf'by teri'ere with the movement of the shackle during the insertion but should an attempt be made to withdraw the shackle, the pawls will spread outwardlyinto binding engagement with the shoulders 2 of the shackle arms and thus prevent such withdrawal. A spring 13 may be coiled around the other pin 11 and have its arms connected to the two pawls 12, thus giving such pawls a tendency to move in outward directions.

lVith the purpose in view of connecting a sealing device with the seal, the front wall of the seal may be provided with two overhanging' portions 14 spaced from the front wall of the casing, being in this instance formed by providing extensions on the side walls 7 of the iirst described casing member and bending such extensions over the front wall 9 in spaced relation to the latter.

The sealing device comprises in this instance, the main body portion 15 on which the identifying' matter 16 is marked and a laterally turned portion 17 at one end of the ,body portion. This laterally turned portion being formed with two openings 18, so that when the body portion 15 of the sealing device is placed beneath the overhanging portions 14, the laterally turned portion 17 will abut the top wall 5 of the casing and the openingsV 18 in the said laterally turned portion will be in position to permit the arms of the shackle to be passed through said openings in order to interlock with the casing, thus securing the sealing device in position on the casing of the seal` F rom the foregoing it will lbe seen that there has been provided a seal in which the shackle may be moved inwardly in the casing of the seal until a portion of the structure to be sealed is firmly secured between the top wall of the casing and that portion of the shackle which connects the arms of such shackle, thus preventing the introduction of a rod or bar between the shackle and the casing for the purpose ot removing the casing from the shackle. The shackle at the 'same time holds the sealing device on the seal casing and the edges of the sealing device are protected by overhanging pro .jecti'ons on the seal casing. rihe ends of the shackle project from the bottom of the seal casing and this permits the withdrawal of the shackle arms from the casing if the Copies of this patent may be obtained for shackle be cut at two points adjacent to the end between the arms. This arrangement makes it possible for the seal casing, which is the most expensive part of the seal, to be used again and again; the only part 0i' the seal that is destroyed being the shackle which may be inexpensively manufactured.

vVhat l claim as my invention and desire to secure by Letters Patent is 1. A seal lock comprising a closed casing, a shackle, devices inclosed by the casing for holding` the shackle therein, a sealing device separate from the casing and having two portions, one coperating with the closed wall of the casing and another extending laterally therefrom and cooperating with that wall of the casing through which the shackle operates, said laterally extending portion having an opening through which a portion of the shackle passes, and overhanging inwardly turned retaining guides at opposite sides of the casing for engaging the edges of that portion of the sealing device which coperates with the closed wall.

2. A seal lock comprising a casing having a top wall formed with openings, and a front wall provided with overhanging retainers, a U shaped shackle fitting through said openings in the top wall, and a 'sealing device removably held beneath such retainers and having a laterally turned portion arranged above the top of the casing and engaged by the shackle to hold the sealing device against removal from the casing.

3. A seal lock comprising two casing members rigidly secured together, one or" said members being formed with a back wall, a top wall, a bottom wall and two side walls formed with inwardly turned extensions, and the other of said members being formed with a closed iront wall and two side. walls received within the side walls of the first named member, the inwardly turned extensions on the irst named member overhanging the front wall ot' the first named member, but being spaced from such front wall to provide retainers for a sealing device, in combination with a shackle operating through the top wall of the irst named member, and a sealing device received under the inwardly turned extensions and held by the shackle.
